AUGUST WALDER, OF ARCH-BOLD, OHIO.

FLUID-T-IGHTROTABY 10mm Eon PIPES.

To all whom it may concern: Y

I e it known that 1, AUGUST WALDER, a citizen of the UnitedStates, and a resident of Archbold, in the county ofFulton and State of Ohio, have invented a certain new and useful Fluid-Tight Rotary Jpint for Pipes; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to whichjit appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form apart of thisspecitication.

My lnvention relates to a rotary joint or connectlon for steam or other pipes containng fluid under pressure and has for its obpet the provision of a simple and eflicient joint of this character which is adapted to form a fluid tight connection between the contiguous ends of two pipes and at the same t me to permit suchpipes to have free relat1ve turning movements.

The operation, construction and arrangement of the parts of the invention are fully described in the following specification and a preferred embodiment thereof illustrated in the accompanying drawing, which is a central longitudinal section of two pipes connected by my oint.

Referring to the drawings, 1 and 2 designate two pipes to the contiguous spaced ends of which are threaded the outer ends of the tubular members 3 and 4, respectively. These members are each formed at, their inner ends with annular shoulders or enlargements 3* and 4, respectively, the contiguous end faces of whlch are preferably provided with annular concavcd seats or runways 5, 5 for the interposed balls 6. A sleeve 7 encircles the enlargements 3 4 of the members 3, 4 and has one end portion thereof threaded to the enlargement 3*, as at 8, and its opposite end reduced, as at 9, to closely encirclethe member 4 without its enlargement. Between the shoulder 10, which is formed by reducing the end of the sleeve 7, and the shoulder 4 of the member 4 are disposed a set of balls 11, said shoulders )referably having their contiguous faces annularly concaved or recessed to rovide suitable runways for theballs. Lea age is prevented between the 1nember4. and reduced end 9 of the sleeve 7 bya suitable packing ring 12, which is pressed closely to said member and to the reduced end of the sleeve by a Specification of Letters Patent.

gland 13, which isthreaded, to said reduced Part e as ow 14 designates a nut which, is threaded into the large end of the sleeve 7 and ontot e member 3 and adapted to loclg the sleeve 7 in adjusted position relativeto the member 3. To overcome any, leakage which might otherwiseoccur between the sleeve 7 and the member 3 or its'shoulder a suptablepackin 15 s pos d be wee he houl e as n nut 14 asshown.

It is evident. wlth this, construction that hem mh r and; new-sa ed, Pip ar I)??? t d e aveiree. t rnine aer men sr tive to the member 3, the sleeve 7 and the packing parts, and that the opposing thrusts of the shoulders 3 4 and 10 against the sets of balls 6 and 11 ma be adjusted to a nicety to prevent longitu inal play between such partsbut to permit a free turning thereof by a turning of the s leeve-7 on the shoulder 3'.

I Wish it understood that my invention is not limited to use in any particular connection nor to any specific arrangement or construction of the parts thereof exce t in so far as such limitations are specified in t e claims.

Having thus descri ed my invention, what I claim as new and desire to secure by Letters Patent is 1- V 1. The combination of two pipes, tubular members threaded at their outer ends to the contiguous ends of said pipes and spacing such pipes apart, said members having-their inner ends annularly enlarged, a sleeve encircling said members and threaded to the enlargement of one member andreduced beyond the enlargement of the other member, anti-friction means disposed between the inner faces of the enlarged ends of said members and between the reduced portion of said sleeve and the contiguous face of the enlargement of one of said members, and packing means associated with said sleeve and members to prevent leakage therebetween.

2. The combination of two pipes, mempipes and spacing the same apart, said memers having annular enlargements at their inner ends and provided with channels opening communication between said pipes, a sleeve encircling said members, sair sleeve being threaded at one end to the enlarged portion of one of said members and having its opposite end reduced beyond the enlarged portion of the other member to form a shoulder in opposition to the outer face of such enlargement, balls interposed between the contiguous ends of said members and, between the enlargements of one member and the-shoulder formed by the reduced portion of the sleeve, means threaded into the large.

end of said sleeve to lock it against move- I ment relative to the member to which it. is threaded, packing interposed between said means and the enlargement of the contiguous member to prevent leakage between said member and sleeve, and packing means associated with the reduced end of said sleeve to prevent leakage between it and the contiguous member.

3. The combination of two spaced pi es, members threaded to the contiguous e11 s of such pi es and adapted to open'cornmunication t erebetween, said members having their inner or contiguous ends enlarged to form annular shoulders, a sleeve encircling said members and threaded at one end to one 7 of such shoulders and having its other end reduced beyond the enlargement of .the other member said sleeve having its large end extended eyond the shoulder to which it is threade to cooperate with one of said m cmbers to form a socket, a stufling-box gland threaded to the reduced end of said sleeve,

balls interposed between the contiguous faces threaded 'member 5 against relative movementsi a I In testimony whereof I have hereunto signed myname' to this specification in the presence of two subscrib'im witnesses.
